Angina 2 – 3 FC: what is it?

Coronary heart disease remains the most frequent pathology, affecting people of all ages. Most often it occurs in older people, causing their death. Coronary artery disease has several forms, one of which is angina. What is it?

Angina is a symptom of coronary heart disease. The main symptoms of angina – chest pain and change in heart rate. The immediate cause of the manifestation of such symptoms of oxygen starvation of the heart muscle that does not receive sufficient amount of oxygen by increasing physical activity. That is why the question arose about the allocation of so-called «angina» – an abnormal heart rhythm to a background of increasing physical activity.

To characterize the angina, in medicine, developed a special classification. It was first proposed by canadian cardiologists and highlighted in his classification of four categories (functional classes). This allows you to match patients to one or another category and assign the appropriate treatment of angina.

The basis for categorisation of the load level that can be absorbed by the patient. The first functional class is a stable load, at which a person does not arise malfunctions of the heart, but when the fourth functional class of the patients on the contrary are unable to move any load without a specific response from the heart. The most frequent functional classes 2 and 3.

Patients diagnosed with 2 FC, you feel a sudden acts of irregular heartbeats while you walk for five hundred meters and more. Also provoke angina may and up the stairs to the first floor and above. In most cases, the discomfort is felt while overcoming the height, with a strong drop in temperature (hard frost, unbearable heat), wind or surge of emotion. It is in such moments, the heart needs more oxygen than usual. Doctors say that angina is not provoked by just adverse conditions. In most cases, the determining factor becomes the physical load, while additional factors only reinforce the failing heart.

Angina 2 FC

Symptoms of angina 2 FC depend on the transferred patient stress, activity. Patients who know their limit, often breaking it, gaining additional attacks irregular heartbeat. Some patients, by contrast, are very sensitive to the first urge of angina and have learned to ignore the level of physical activity, which will lead to angina. Thus, they organize their work and leisure so as to avoid situations that provoke angina. Monitoring of patients of the above two groups leads to the conclusion that the severity of angina is not determined by the frequency of acts the strokes and the pressure that a person experiences.

Angina 3 FC

Patients suffering from this type of disease, often limit themselves to the load, in order not to experience unpleasant feelings. Angina is provoked by even walking on a flat road at a speed which is normal. Passed five hundred meters is enough for patients covered progressive angina. For such patients angina can cause external effects (weather conditions, stress, emotional overload). Doctors working with patients in this category, note that there is a condition on the background of coronary artery disease, which affects patients.


Symptoms of angina attacks 2 and FC 3 has a lot in common. Usually failure of the heart accompanied by pain in the heart, has a clear point of origin and end. The relief attack is possible at the termination of the impact load on the body, or by receiving special heart medicines (e.g., Nitroglycerin).

In most cases the pain is localized in the region of the heart, behind the breastbone. It can be clearly limited and diffuse on the entire left half of the chest. By its nature, pain, pressing, constricting, accompanied by a lack of air. Because of these feelings, patients often experience fear of death and become restless and irritable, have a cold sweat.

As you know, a half-hour oxygen starvation of the heart leads to myocardial infarction, so if the symptoms of angina has not stopped after drug treatment or the cessation of stress, you need to call an ambulance to provide skilled assistance in the hospital.

Diagnosis of angina load

To determine the load angina cardiologist is quite simple. To diagnose the disease, a number of studies, electrocardiogram, ultrasound of the heart. If necessary, we can do a coronary angiography to make the diagnosis more clearly. After the physician will decide on the main diagnosis of angina, he would do more research on the definition of the functional class of angina. This will help stress test: the treadmill test, Bicycle ergometry, cold test.

Treadmill test- an informative approach to identify coronary artery disease at an early stage, when even the hardware techniques do not always cope with this task. This test is recommended for all persons who crossed the border fifty years, regardless of the presence of complaints of heart. Besides, the doctors resort to the treadmill test, if necessary, to carry out differential diagnosis of pain in this area.

The real test is to load the heart of the patient to a certain level, when the manifest deviation in his work. Usually the load you give on the treadmill, and to the patient, attach electrodes, which will record the performance of the heart. With their help, the doctor will be able to see when a patient’s heart will begin to work abnormally and stop the load. For measuring the pressure of the patient impose the cuff. The first time the patient is beginning to follow the path, however, three minutes later, the doctor changes the angle of the track relative to the floor and slightly increases speed. At the end of the test the results are interpreted and diagnosed.

Veloergometry – a kind of treadmill test. The essence of the technique is the same load on the heart, it is not only given on the treadmill and on the bike. Cold test consists in dipping hands in a container of cold water or ice cubes, and after some time measured the blood pressure and removed electrocardiogram.

The above-described techniques allow high accuracy to diagnose angina load and assign it a number grade.
